The Conductivity, Temperature and Depth (CTD) and other data were collected in Gulf of Alaska, Chukchi Sea, and NW Pacific (limit-180). Data was collected from cruises HX 161, HX 163, HX 165 and HX 167 of R/V ALPHA HELIX. The data was collected over a period spanning from March 16, 1992 to October 27, 1992. Data was submitted in one exabyte cassette by Dr. Thomas C. Royer, Institute of Marine Science, University of Alaska, Fairbanks, AK. CTD data is available in F022-CTD-Hi Resolution file format of NODC. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

Temperature and conductivity data were collected using moored current meter casts in the North Pacific Ocean from October 18, 1978 to August 1, 1980. Data were submitted by University Of Alaska - Fairbanks as part of the BORAX project. Data were processed by NODC to the NODC standard Current Meter Data (F015) format. The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments.

The Conductivity, Temperature and Depth (CTD); and other data were collected using ship POLARSTERN from Arctic Ocean. The data was collected from August 10, 1993 to September 24, 1993. One diskette of CTD data was obtained based on recommendation of Dr. Robin D. Muench, Earth and Space Research, Seattle. Dr. Muench was a participant in R/V POLARSTERN CRUISE ARK IX/4. The data was collected by Ursula Schauer, German Data Center, Alfred-Wegener Institute, Bremerhaven, Germany.

Conductivity, Temperature and Depth (CTD) and other data were collected in Coastal Waters of California by NOAA Ship DAVID STARR JORDAN. Data were collected over a period from April 10, 1987 to May 23, 1994. CTD Data from 3,380 casts was received from Kenny Baltz of National Marine Fisheries Service, Tiburon, CA via Norm Hall by NODC.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format. The C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.

Conductivity, Temperature and Depth (CTD) and other data were collected as part of Tropical Ocean Global Atmosphere and World Ocean Circulation Experiment. Data were collected from Ships XIANG YANG HONG 05 between November 16, 1991 and December 11, 1991. CTD data from China2 data set containing 164 profiles (164 files) was submitted to US NODC using File Transfer Protocol by National Oceanographic Data Center of the Peoples Republic of China.
